Texas Instruments SN75176AD

The SN75176A differential bus transceiver is a monolithic integrated circuit designed
for bidirectional data communication on multipoint bus-transmission lines. It is designed for
balanced transmission lines and meets ANSI Standard EIA/TIA-422-B and ITU Recommendation
V.11.

The SN75176A combines a 3-state differential line driver and a differential input line
receiver, both of which operate from a single 5-V power supply. The driver and receiver have
active-high and active-low enables, respectively, that can be externally connected together to
function as a direction control. The driver differential outputs and the receiver differential
inputs are connected internally to form differential input/output (I/O) bus ports that are designed
to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These ports feature
wide positive and negative common-mode voltage ranges making the device suitable for party-line
applications.

The driver is designed to handle loads up to 60 mA of sink or source current. The driver
features positive- and negative-current limiting and thermal shutdown for protection from line
fault conditions. Thermal shutdown is designed to occur at a junction temperature of approximately
150°C. The receiver features a minimum input impedance of 12 kΩ, an input sensitivity of ±200 mV,
and a typical input hysteresis of 50 mV.

The SN75176A can be used in transmission-line applications employing the SN75172 and
SN75174 quadruple differential line drivers and SN75173 and SN75175 quadruple differential line
receivers.
